ILLINOIS, AND JOSEPH REIF, IR, OF THE IIEROULES WOODENWARE COM- IVIACHINE FOR MAKING SLAT-AND-WIR EFABRIC.

SPECIFICATION forming part of Letters Patent No. 609,387, dated August 16, 1898.

Application filed April 25, 1893- To a, whom it may concern: I

Be it known that we, GEORGE P. FISHER, Jr., a resident of Chicago, in the county of Cook, State of Illinois, and JOSEPH REIE, Jr. a resident of I-Iebron, in the county of Porter, State of Indiana, have invented certain new and useful Improvements in Machines for Making Slat-and-Wire Fabric, of which we do declare the following to be a full, clear, and

exact description.

The invention has relation to that class of machines commonly known as slat-andwire fabric weaving machines, in which slats, usually of wood, are connected together in series by suitable wires. 7

The invention consists in the various im provements hereinafter described, illustrated in the accompanying drawings, and'particularly pointed out in the several claims at the end of this specification. M

The frame A of the machine will be suitably constructed from woodor metal (preferably cast-iron) to 'sustainthe various parts of the mechanism.' Between the side bars of the frame extend the cross-bars a a, (see I of the fabric.

Fig. V,) whereon is journaled the main driveshaft B, the outer end of this drive-shaft having keyed thereto a beveled gear-wheel 2, that engages with the pinion 3 upon a short shaft 4, sustained within suitable bearings 5 and carrying pulleys 6, 7, and 8. The pulley 6 is for driving the cutter-head shaft, as will be hereinafter described, and the pulleys 7 and 8 are respectively fast and loose pulleys adapted to receive the drive-belt, by which motion will be transmitted to the machine from a suitable source of power. Upon the inner end of the shaft B is fixed a beveled pinion 10, that meshes with a beveled gearwheel 11, that is fixed to a counter-shaft O, the ends of this counter-shaft being journaled within suitable boxes 12 upon the side bars of the main frame. Upon the counter-shaft C are keyed the cam-wheels O and C each of these cam-wheels being furnished with cam grooves or ways 0, as clearly shown by Fig. IV of the drawings. The cam-groove c of each of the cam-wheels O and (1 receives a friction-roll 1 1, that is carried by and projects laterally from the end of a shifting lever D. Preferably there are two shifting levers D and preferably, also, two cam-wheels, as shown, and the levers D are pivotally sustained by lugs 13, projecting inwardly from a cross-bar of the main frame, (see Figs. IV and V,) while the upper ends of the levers D are perforated to receive the ends of the rods 15, the opposite ends of which rods connect with the ends of the drive-barE, (see Fig. 1,) whereby a reciprocating movement will be imparted to the spindles F, that serve to twist'together the wires that connect the slats Each of the spindles F has its rear end provided with an enlargement f, around which is formed an annular groove to admit a rib 6, (see Figs. VIII and X,) projecting inwardly from the drive-bar E. The

drive-bar E is shown as formed of upper and the spindles may be adjusted transversely in order to enable the wires to be spaced any desired distance apart.

From the enlargement f at the end of each "spindle project the rods 21, that pass through holes formed in the cross-head 22 at the inner end of a spool-carrier 23, that is revolubly mounted upon a tubular shaft 24:. The rear end of the shaft 2et is fixed within a sliding head-block 25, being preferably held in place by a set-screw 26, and the inner end of the tubular shaft 24: is provided with a collar 27 to prevent the longitudinal movement of the spool-carrier 23. The head-block 25 is preferably of casting, having at its top a raised rocating movement to the spindles F.

the main frame of the machine at its front end. Holes are formed in the base of the head-block 25 to admit the adj Listing-bolts 29, the hooked ends of which engage the lower portion of the transverse bar, whereon the head-block rests, as clearly seen in Fig. VIII. Each of the spool-carriers 23 is provided with a pivot-bolt 30, whereon is journaled a spool 31, that carries the small wire 32, (commonly termed the tie-wire,) whereby the slats are fastened to the main wire 33, that passes through the tubular shaft 24: and through the center of the corresponding spindle F.

By reference to Figs. I and VIII it will be seen that the main wire 33 passes through a central hole f in the head of the spindle F, while the binding-wire 32 passes through a channel f in the wall of the spindle F and through a continuation of this channel f in the spindle-head, the outlet of the channel f being considerably at one side of the center of the spindle-head. By reference to Figs. VI and VIII it will be observed that the holes or channels f and f are connected bya crosschannel f the purpose of which will be hereinafter set forth.

From the construction of parts as thus far defined it will be seen that when revolution is imparted to the main drive-shaft B and from it to the counter-shaf t G the cam-wheels G and C will be revolved, and as these camwheels revolve the driving-levers D will be shifted back and forth from the position shown by full lines to the position shown by dotted lines in Fig. IV of the drawings. As the driving-levers are thus oscillated they will carry forward and backward the drivebar E, which bar in turn will impart a recip- It will also be apparent that as the spindles F are thus reciprocated the arms 21 at the ends of these spindles will slide freely through the crossheads 22 at the inner ends of the spool-carriers 23. It is obvious, however, that when revolution is imparted to the spindles F by mechanism to be next described corresponding revolution will be transmitted through the arms 21 to the spool-carriers 23.

Upon each of the spindles F and between the journal-boxes 16 of such spindles is mounted a sprocket-wheel 10, this wheel being provided with a key adapted to fit in a long seat or slot a1, formed in the outer face of the side wall of the spindle, (see Figs. VIII and IX,) so that while the sprocket-wheel 10 serves to impart revolution to the spindle it permits the spindle to slide back and forth through the sprocket-wheel. \Vith the sprocket-wheels 40 of each of the spindles F engages a sprocketchain 42, this chain being preferably passed around the sprocket-wheels 40, as indicated in Fig. IX of the drawings, so as to impart rotation to the spindles in opposite directions.

Upon the top of the frame 17 rise suitable journal-bolts or standards 44, the upper ends of which carry a shaft 45, whereon is mounted an idler sprocket-wheel 46, over which the chain 42 passes, and at the end of the frame 17 is journaled a shaft 47, on which is loosely mounted a sprocket-wheel 48, around which the chain 42 also passes. Inasmuch as the spindles F will be revolved only at intervals, it will be understood that a suitable clutch mechanism will be interposed between the spindles and the constan tly-driven parts of the mechanism, and the preferred form of clutch mechanism is that illustrated more particularly in Figs. XVI to XXI of the drawings. The shaft 47, whereon the sprocket-wheel 48 is journaled, is bolted, as at 49, to the crossframe 17, and upon the shaft 47 is revolubly mounted a sprocket-wheel 50, from which a sprocket-chain 51 leads to a sprocket-wheel 52, that is keyed upon the main shaft B, as clearly seen in Fig. II of the drawings. The hub of the sprocketwheel 50 is preferably screw-threaded, as at 53, to enter a correspondingly-threaded opening in the detentwheel 54, that revolves constantly with the sprocket-wheel 50. Upon the shaft 47 and between the sprocket-wheels 48 and 50 is mounted a disk 55, having an annular lateral flange 56, that is connected, as bya set-screw 57, with the hub of the sprocket-wheel 48. Upon the opposite side of the disk 55 is formed a segmental flange 58,- (see Fig. XXL) against which bears a coil-spring 59, that is carried bya stud projecting from the short end of the detent-lever 61, that is pivoted, as at 62, upon a pin projecting from the side of the disk 55. The detent-lever 61 carries at one side of its longer arm a friction-roll 62, adapted to engage with the teeth or notches of the detent-wheel 54, as seen in Fig. XX of the drawings, being held in such engagement by the coil-spring 59. The detent-lever 61 is formed with a lug 63, adapted to be engaged by a hook or projection 64 on the end of a latch-bar 65, that is pivotally connected, as at 66, to the under side of the frame 17. Upon the rear end of the latch-bar 65 is a stud carrying a coil-spring 67, that bears against the under side of the frame 17 and tends to normally hold the latch-bar in the position seen in Figs. XIX and XXI of the drawings. Upon the side of the latch-bar 65 is formed the short lateral arm or extension 68, (see Fig. XXIL) against which bears a coil-spring 69, the opposite end of which encircles a stud projecting from a catch that is pivoted, as at 71, to the frame 17. Catch 70 is designed to engage with a notched shoulder or offset 72 on the periphery of the disk 55, and this engagement will occur when the hooked end 64 of the lever 65 engages with the offset 63 of the detent 61, and the purpose of the catch 70 is to prevent any backlash or reverse motion incident to the sudden stopping of the spindles, as will presently more fully appear.

To the latch-bar 65 is pivot-ally connected,

pin 78.

as at 74, a rod 75, the lower end of which rod is pivotally connected, as at 76, (see Figs. II and IV,) to a tripper-lever 77, that is pivotally sustained on a pin 78, passing through lugs that rise from the cross-bar a of the main frame. The tripper-lever 77 is formed with a series of holes 80, through any one of which a pin 7 8 may be passed, the purpose of these holes being to adjust the tripperlever in order to determine the time of action of the clutch mechanism,and consequently the number of revolutions of the spindle, as will hereinafter more fully appear. The outer or free end of the tripper-lever 77 extends adjacent to the side of the cam-wheel C, (see Figs. I and IV,) and this side of the cam-Wheel is provided with a stud or other suitable projection 82, (see dotted lines, Fig. IV,) adapted to contact with the under side of the tripper-lever 77 and lift the same as the cam-Wheel O revolves. It is obvious that as the cam-wheel C revolves in the direction of the arrow in. Fig. IV it will strike the under side of the tripperlever 77 and rock this .lever about the pivot- As the outer end of the tripper-lever 77 is lifted the inner end will be depressed and will draw down the rod 75, causing this rod to draw the latch-bar 65 downward until its hooked end 64 passes from engagement with the shoulder or oifset 63 on the detent 61. (See Figs. XIX, XX, and XXI.) \Vhen the hooked end 64 of the latch-bar 65 has been withdrawn from engagement with the shoulder 63 of the detent 61, the coil-spring 59 will rock the detent 61 about its pivot and cause the roller 62 to engage with the scalloped clutch-wheel 54. Inasmuch as the clutchwheel 54 is fastened to the constantly-revolving sprocket-wheel 50, it is manifest that rotation will immediately be imparted through the detent 61 and the disk 55 to the sprocketwheel 48, and from this sprocket-wheel revolution will be imparted by the sprocket-chain 42 to the sprocket-wheels 40 upon the spindles F. (See Fig. IX.) It will also be seen that the detent 61 will remain locked to the clutchwheel 54 so long as the hooked end 64 of the latch-bar 65 remains in retracted position, which will be determined by the length of time that the stud or offset 82. of the camwheel 0, Fig. IV, is in engagement with the free end of the tripper-lever 77. be seen that by inserting the pin 78 in any one of the holes 80 of the tripper-lever the length of time during which the stud or offset 82 shall hold the tripper-lever in raised position may be varied, and consequently the time during which the clutch shall cause the spindles F to be driven may be correspondingly varied. In this way the number of revolutions imparted to the spindle during each revolution of the cam-wheels C and C may be determined, and by this means the number of coils of the small tie-wircs 32 about the main binding-wires 33 may be varied and the distance between the slats of the fabric may be regulated.

Itwill also i By reference more particularly to Figs. I, IV, and VI of the drawings it will be seen that if the spindles are in the retracted position there shown and a slat V be fed in front of the spindles and the cam-wheels O and C have revolution imparted thereto in the direction of the arrow in Fig. IV the cams will first rock the levers D, so as to cause the spindles to move from the position shown by full lines, Figs. IV and VI, to the position shown by dotted lines, and as the spindles are thus moved they will advance the slat N and at the same time advance any slats that may have been previously fed into the machine. About the time that the cams 0 have moved the spindles to the position shown by dotted lines the stud or offset 82 on the cam-Wheel C will rock the tripper-lever 77, and the rockin g of this tripper-lever will cause the latchbar 65 (see Figs. XIX to XXI) to be disengaged from the detent 61, and the spring 59 will cause the detent 61 to engage the clutchwheel 54 and lock the constantlyrevolving sprocket-wheel 50 with the sprocket-wheel 4S, and through the medium of the sprocket-chain 42 revolution will be imparted to the spindles F and the small tie-wire 32 will be wrapped around the main binding-wire 33. The revolution of the spindles F will continue until the stud or offset 82 passes from engagement with the under side of the tripper-lever 77, when the tripper-lever will again drop to the position shown by full lines in Fig. 1V, and the spring 67 will cause the hooked end 64 of the latch-bar 65 to move upward into position to engage the shoulder or offset .63 of the detent 61, thereby rocking the detent about its pivot and causing the roller 62 to pass from engagement with the scalloped clutch-wheel 54. The lifting of the latch-bar 65 will also cause the pivoted catch to move from the position seen in Fig. XX to that seen in Fig. XXI, and in this position the free end of the latch 7 0 will engage with the shoulder or offset 72 on the disk 55, and thus prevent any backlash or reverse motion of the parts incident to the sudden stoppage of the spindles.

By reference to Figs. VI and VIII of the drawings it will be observed that the free ends of the spindles F are provided with vertical grooves f and it will be seen that as the spindles revolve to twist the tie-wires 32 around the main binding-wires 33 the tie-wires will be drawn into the channels or grooves f These grooves or channels f thus serve to lay the tie-wires 32 around the main bindingwires 33 evenly and prevent the piling up of the coils of the tie-wire one upon another, as would be apt to occur were no such vertical grooves between the channels of the tie-wires and binding-wires provided. It is obvious that the revolution of the spindles F, and consequently the wrapping of the tie-wires upon the binding-wires,will continue so long as the stud or offset 82 is in engagement with the tripper-lever 7 7 5 but the revolution of the spindles F will cease when the stud 82 passes from engagement with the tripperlever 77. As soon as the stud or offset 82 passes from engagement with the tripper-lever 77 the cams 0 will operate to rock the levers D from the position seen by dotted lines to the position shown by full lines in Fig. IV, and the spindles F will be in like manner retracted to the position seen by full lines in Fig. VI, so that a new slat may be fed in front of the spindles. The parts of the machine are so relatively arranged that the spindles F shall stop with the wires 32 and 33 in vertical alinement, as seen in Fig.VI, so that the slats can be fed into the spaces between the wires.

The mechanism whereby the automatic feeding of the slats is effected will next be described.

At the top and extending to one side of the main frame is a suitable rack or hopper, wherein will be held the slats W to be fed into the machine. This rack or hopper comprises a base or support H, (see Figs. 1, II, XI, XII, and XIII,) that may be formed from a beam of wood suitably bolted to the main frame, and in the construction shown this beam H extends inward partially over the main frame. The sides of the hopper are preferably formed of vertical rods V, the rods at one side having their tops preferably bent or flared, as at u, (see Fig. I,) so as to permit the more ready insertion of the slats W into the hopper. The end of the hopper is shown as comprising a plate M, that rises from the support H of the hopper. (See Figs. II and XXIII.) The bottom of the plate M is formed with an opening an to permit the slats to be fed from the hopper, and preferably a suitable gate M will be placed inside the hopper adjacent to this opening in order to regulate the size of the opening in conformity to the thickness of the slats that are fed into the machine. The gate will be adjustably attached in the usual manner to the inner face of the plate M.

011 top of the main frame, at the side opposite the slat-hopper, is placed a slat-support 90, that is bolted to the top of the'main frame,

the upper surface of this support 90 being in line with the top of the support II, as clearly seen in Fig. II. From the surface of the support 90 rises a ledge 91, (see Figs. II and XXIIL) that serves as a stop or guide for the ends of the slats WV. From the top of the supports H and 90 extends the table 93, the surface of which is flush with the upper surface of the supports II and 90, this table 93 being sustained by the side rails 94, (see Figs. XXIII and XXV,) that rest upon the top .frame of the machine and upon a suitable cross-bar 95, that is sustained by the legs 96. (See Fig. XXIV.) At each side of the top of the table 93 and runninglen gthwise thereof is placed a rabbeted guide 97, beneath which the ends of the slats will pass and which serves to hold the slats against the surface of the table as they are successively pushed along. (See Figs. VI, XXIII, and XXIV.)

The upper surface of each of the supports H and 90 is provided with a raised shoulder it (see Figs. XXIII and XXVI) to aid in guiding the slats as they are delivered from the hopper into the machine.

Above the surface of the support 90 and of that part of the support II extending over the top of the main frame (see Figs. I and II) is a presser-bar K, one end of which is provided with a spring-latch 70, adapted to engage with the notch or seat in the end plate M of the slat hopper or rack. The opposite end of the presser-bar K is formed with a slotk adapted to receive a retainingbolt 100, that is pivoted, as at 101, to the support and is provided with an adjustingnut 102, a spring 103, and a Washer104c, whereby the pressure of the bar K may be regulated. The end of the bar K is rounded, as seen in Fig. II, so that the retaining-bolt can be swung freely into and out of engagement with the bar, and when the bolt 100 is disengaged from the bar the bar can ,be raised so as to permit the spring-latch 7a to be withdrawn from the notch or seat It in order that access may be had to the underlying parts of the machine.

By reference more particularly to Figs. II,

XI, and XII of the drawings it will be seen that the support H is formed with a long channel h adjacent the inner end of which is journaled a sprocket-wheel 110, and at the outer end of the support H and preferably extending Within the channel 77, are the arms of a bracket 112, that sustains a sprocketwheel 113. The bracket 112 has its arms provided with the long slots 114, through which pass the bolts 115, suitable spaceblocks 116 being carried by the bolts, so that the bolts will serve to securely hold the bracket in place. The long slots 114 permit the adj ustment of the bracket 112 and sprocket-wheel 113, for the purpose to be presently stated, and preferably also the sprocket-Wheel may be adjusted by inserting its pivot-bolt in either of the several holes therefor, as shown in Fig. XII. Within the channel 72. of the support II is mounted a shifting table L, that is mounted upon swinging links L,

the lower ends of these links being pivoted,

' as at 118, to the support H, while the upper ends of the links are pivoted, as at 119, to the table L. (See Figs. II, XI, and XII.) One of the links L is preferably provided with a handle L whereby the shifting of the table L may be effected manually when desired. Over the sprocket-wheels 110 and 113 and around a sprocket-wheel120, that is keyed upon the main drive-shaft B,passes a sprocket feed-chain 121', that carries one or more feeddogs 0. Each of these dogs 0 is pivoted to upright arms 122, that rise from certain links of the chain 121, (see Figs. XIV and XV,) and preferably the dogs 0 are formed with the slots 0, through which pass the ends of a pin 121, that serves to retain the corresponding dog against displacement. Each of the dogs 0 is preferably chambered, as seen in Fig. XV, and is formed with feet or ledges 0 adapted to ride upon the surface of the table L, Fig. XI. The top of each dogO is formed with a shoulder 0 adapted to engage with the outer end of the lowermost slat W within the hopper. By reference toFigs. XI, XXIII, and XXV it will be seen thatupon the top of the support H are placed the metal strips 130, that serve to partially close the channel 71, of the support II, leaving simply room for the easy passage of the shouldered portion 0 of the dog 0, and upon the plates 130 the mass of slats W will rest.

From the foregoing description it will be seen that when revolution is imparted to the main drive-shaft B (see Fig. II) correspond ing revolution will be given to the sprocket wheels 110 and 113,0ver which passes the feedchain 121, thus causing the dogs to move in the direction of the arrow, Fig II, and over the table L, which normally occupies the position shown by full lines in the drawings. As the dogs 0 successively pass onto the outer I end of the table L the shoulders 0 of the dogs will engage the outer end of the lowermost slat W, thereby forcing this slat through the opening m of the hopper and across the surface of the supports 11 and 90, as clearly shown in Figs. II and XI of the drawings. As the dogs 0 pass onto the table L the feet 0 of the dogs will bear upon the table, thus holding the dogs in the elevated position seen in Fig. XV of the drawings. As soon, however, as the feet o of the dogs pass from off the inner end of the table L the weight of the dogs will cause them to turn about their pivots and the shoulders 0 to drop from the engagement with the slat W. In this way each slat can be deposited with exactness at the proper point in front of the spindles F. If desired, the inner end of the table L may have an adjustable plate thereon in order to vary the point at which the dog shall release the slats. It will be understood, of course, that the dogs 0 will be set at such points that the slats W will be delivered into the machine while the spindles F are in the retracted position shown by full lines in Figs.- I, II, VI, and XXIII of the drawings, and the sprocket-wheel 120 will be of proper size and the chain 121 of proper length to insure the movement of the dogs in correspondence with the movements of the spindles.

After a slat has been delivered by one of the dogs 0 immediately in front of the spindles F, as shown by full lines in Figs. II and VI and by dotted lines in Fig. XXIII, the spindles will be advanced by the cam-wheels C and 0 thereby moving the slat onward, and at the same time pushing onward all slats that have been previously fed into the machine. It will be understood, of course, that as the dogs 0 introduce the slats into the machine the ends of the slats will pass between the large and small wires, as clearly seen in Fig. VI of the drawings. When the spindles IIO F have advanced the slats, revolution will be imparted to the spindles, as hereinbefore described, causing the small wire 32 to be wrapped about the large wire with the proper number of coils, afterwhich the spindles F will be withdrawn and a new slat will be fed in.

The machine shown in the accompanying drawings, while adapted for the manufacture of slat-and-wire fabric for any of the purposes for which such fabric is ordinarily employed, is more especially designed for man ufacturing the fabric to be used for the bodies of barrels, and in order to properly croze or trim the ends of the slats the mechanism next to be described is employed. Across the main frame of the machine, and preferably supported upon pillow-blocks 140, mounted upon the ends of the side rails 94, extends the shaft P, carrying cutter-heads P, that are provided with suitable knives 19, adapted to form the croze and shape the ends of the slats to form the chime of the barrel. The cutter-heads P will be of any usual or suitable construction and need not be particularly described. Upon the outer end of the shaft P is a pulley 142, from which leads a belt 143 to the large pulley 6, that is keyed to the shaft 4. (See Figs. I, V, and XXIV.) Above the cutter-heads P extend the hoods 145, preferably of sheet metal, and partially encircling the cutter-heads, and preferably the supports H and 90 will be formed with cut-away spaces 146 for the discharge of thechips from the cutter-heads. (See FigpXXIlI.) One of the hoods 145 is shown as attached to the presser-bar K, (see Figs. I and XXIV,) While the other hood 145 is provided with a flange that will be connected to the plate M of the hopper. (See Fig. II.)

While the construction of the cutter-heads is not novel, the arrangement of cutterheads so that the crozing of the slats will be substantially effected before the twisting of the Wires is a feature of importance. In machines heretofore used for the manufacture of slat-and-wire fabric for barrels it has been customary to locate the cutter-heads in such position as to croze and trim the slats after the twisters or spindles that operated to bind the slats together. This construction has been found objectionable because of the tendency of the cutter-heads to jam the slats together, and thus destroy the accurate spacing of the slats. By locating the cutter-heads in such position that the crozing of the slats is completed, or approximately so, before the wires are twisted about the slats all danger of jamming the slats together or varying the spaces between them is avoided. For this reason it will be seen, by reference more particularly to Fig. VI of the drawings, that the spindles F have such extent of movement that they will advance the slats practically beyond the path of the cutter-heads before the twisting of the wires occurs.

In order to aid the spindles F in advancing the slats beneath the cutter-heads, it is preferred to employ the feed-arms R and R, (see Figs. I and XXIIL) the outer ends of these arms being connected to the drive-bar E, while their inner ends extend over the frame 17 and between the presser-bar K and the surface of the supports 90 and H, whereon they rest and are supported in manner free to slide. Preferably the inner ends of the bars R and R are formed with the angular portion 1" to afford a broader bearing upon the edges of the slats, and pins 1' maybe pro- Vided to aid in guiding the bars R R. The bars R R are so located as to bear upon the edges of the slats very close to the path of the cutter-heads P", and thus more effectively aid in presenting the slats to the action of the cutter-heads. Across the top of the main frame, beyond the cutter-heads, is extended a bar 150, to which are bolted the presser-feet 151, that are preferably formed of spring metal, with their free ends slightly upturned, as seen in Figs. I and XXIV, to permit the slats W to be advanced beneath the presserfeet. These presser feet are arranged in close proximity to the cutter-heads and serve to hold the slats down during the crozing operation and will also aid in preventing any reverse movement of the slats as the spindles are retracted.

In order to divide the woven mat or fabric into proper lengths to form barrels or like packages, the mechanism next to be described is preferably employed. Upon suit-- able rods 160, that are supported in any convenient manner-as, for example, by the frame 17 at one end and a bar 161 depending from the table 93 at the other end, (see Figs. XXIII and XXVII,)-is mounted in manner free to slide what, for convenience, are termed the dummies S and S. (See Figs. XXVII and XXIX.) At each side of the dummies S S are arranged the hubs 162 of the dummy-frame, the side bars 163 of this frame being connected by a web orplate 164. Upon pins 165, that extend between the side bars 163 of the dummy-frame, are pivotally mounted the levers 166, the lower portions of these levers being provided with teeth 167, that mesh with corresponding teeth 168, formed upon the lower portions of the dummies S S. The dummies S S, it will be understood, are free not only to slide on the rods 160, but are also pivoted upon these rods, so as to, turn from the position seen in Fig. XXVIII to the position seen in Fig. XXIX of the drawings. To one side of the dummyframe is connected a rope or cable 170, (see Figs. I, III, IV, XXIII, and XXVIL) that is trained over a pulley 171 at the front of the main frame, and to this rope 170 is connected a weight 172, that serves to normallyhold the dummies in the idle position shown in Figs. XXIII and XXVII of the drawings. Preferably cushion springs 17 1 will be mounted upon the rods 160 in order to relieve the jar as the dummy-frame is retracted by the weight 172, as will presently more fully appear.
